304 Food Grade Stainless Steel

Machine Rated Power: 350W

Capacity: 3-6 kg/h

Supply Voltage for Use: 220V ±10% AC 50/60Hz (110V ±10%

60Hz is suitable for Taiwan, Japan, Korea, Canada, the United States. Please

refer to the identity next to the power outlet in the rear part of the machine.)

Pressing Speed (reference value): 3Kg/hour; the more moisture raw materials

contain, the slower the speed will be; the larger the particle size (big pumpkin

seeds, camellia seeds and large peanuts) of raw materials is, the slower the

speed will be.

Maximum Pressing Particle: the press barrel of U.S. Solid Oil Press is designed

based on the volume of a peanut. If the particle size exceeds this, particles

should be smashed before the pressing to make the volume no greater than

that of peanut kernel (camellia seeds should be processed in this way).

Suitable for pressing: peanut,sesame,rapeseed,walnut,soy,sunflower,water-

melon, seeds, pumpkin seeds ,almond, hazenut, pine nut, flaxseed and so on.

(cold pressing is only applicable to flaseed)

This machine do no't support olive,perilla seeds,hemp seeds,camellia seeds,

pepper seeds and castor beans. And for nuts,you should remove the shell and

cut the nuts in pieces.

XII. Specications

U.S. Solid® • 1200 E.55th Unit C, Cleveland, OH, 44103 • www.ussolid.com

• Always use a grounded outlet.

• Only press raw materials discussed specically in this manual.

• Do not press the dry residue, as it can lead to blockage in the pressing chamber.

• Never use an induction cooker, light wave stove, or electric radiant cooker to re

or heat raw materials. It will damage the raw materials and cause the press to

produce only powder.

• The taphole should always remain open to allow spillage in case of overly damp

raw materials.

• This machine should only be operated by adults who have read and fully

understood this manual.

• Never allow operation of this equipment by children.

• Only raw materials mentioned in this guide should be placed in the pressing

chamber. Hard objects or other materials could damage the machine.

• Avoid pressing wet materials. They will block the pressing chamber.

• Do not put ngers or any other objects into the pressing chamber to stir the raw

materials. This could lead to serious injury and/or damage to the machine.

• Do not press materials after being overly dried out; if only powder comes out

during pressing, the material is too dry. This can lead to blockages in the machine.

• When heating in the microwave, be sure to use a microwave safe plate or

receptacle.

• Only camellia seeds should be fully roasted. All other raw materials can be roasted

to a medium-well level. Make sure to press raw materials while still warm to

maximize oil production. Once materials cool, the oil will be greatly reduced or

only powder will come out.

II. Safety Notes

Problem: The electric motor buzzes and shakes.

Cause:

• The motor is jammed.

Solution:

• Stop pressing immediately and remove raw material from hopper.

Preheat for one hour and then press “Clean” for up to two seconds ,then

press “Start” for one second. Repeat and the lever will ease out. If still

stuck, take out the press barrel, put it on the gas stove over a low ame,

and dry the dross hole (6 cm long) of the press barrel until raw materials

inside are burnt up. In the process, you will hear a squeaky sound. Then

you can reinstall the press barrel on the oil press, screw on nuts, and

press “Clean.” USE CAUTION to avoid burns and bodily harm.

Problem: The machine is making a sharp metallic noise.

Cause:

• Materials are not entering the barrel evenly. You should allow it to con-

tinue to run two or three minutes and the noise will disappear as the raw

materials redistribute in the press barrel. If the metal friction sound still

occurs, then the raw materials are damp and sticking to one side of the

screw.

Solutions:

• If raw materials are only partially damp, you can counteract this by

adding soy beans to draw out moisture from the raw materials until the

sound disappears.

• Remove the press barrel, clear away the raw materials that are stuck on

the screw, and then dry the barrel.

• Replace moisture retaining raw materials with heated raw materials(ac-

cording to the above method of heat pressing).

Problem: Powder begins coming out during the middle of the pressing

process.

Causes:

• Too much raw materials was heated at one time.

• Raw material was allowed to cool after heating.

Solution:

Heat about two pounds each time. When the pressing is about to nish,

you can heat a new batch. Cover raw materials when pressing, especially in

winter.

III. Unpacking the Oil Press

Opening the Oil Press

First check whether there is damage due to transportation. Make sure the aluminum

heater cover stays close to pressing chamber. Otherwise clogging will occur and no oil

will come out!

As for the manufactured equipment: there may be discoloration or unevenness in the

surface of the pressing chamber. This is the normal appearance of unique, wear-resis-

tant metals and is normal with new products.

Packing items include one manual, one wrench (for removing the pressing chamber),

one material hopper, one power cord, one oil cup (gift), one slag net (gift) and one

hard round brush (gift); consult the website for any changes to gifts, as these can

change without notice.

Parts of the Oil Press

Figure 1 shows the panel of switches. The switch on the far left can toggle between

cleaning and squeezing. The red switch is the power switch. When on, the machine will

be heating, or it can be turned o. The small red button is overload protection. In the

bottom right, there is a label highlighting the wattage of your machine.

Figure 1

Problem: During pressing, lots of residue in the oil outlet.

Causes:

• The preheating switch is not on or was not left on long enough.

• Raw material contains too much water or the moisture was not properly

removed.

• Incorrect frying where the surface is burned but internal parts are still

raw.

Solutions:

• Replace raw material.

• Heat raw material according to instructions in this manual.

Problem: Oil will not properly separate, even after a few days.

Causes:

• Raw materials have been stored in excess of one year or raw materials

have been treated with chemicals while in storage.

• Raw materials became brittle after being heated.

• Incorrect heating where the surface is burned and internal parts are still

raw .

Solutions:

• Replace raw material.

• Heat raw material according to instructions in this manual.

Problem: Oil and residue spill simultaneously from the dross hole.

Cause:

• The raw materials contain too much moisture.

Solutions:

• Press with some soy beans to draw moisture from the raw materials.

Start with a small amount and add more as needed.

• Fire the raw material according to the above method of heat pressing.

Problem: Oil ows back from the base of the press barrel during pressing.

Cause:

• Raw materials are damp.

Solution:

• Dry raw materials in the sun or heat them in the microwave or oven until

they are dried out.

U.S. Solid® • 1200 E.55th Unit C, Cleveland, OH, 44103 • www.ussolid.com

In Figure 2, the hopper will be where all raw materials are held

for pressing. Take careful note of the heater, as this element can

be quite hot, and lead to burns or other injuries if the user is not

careful. The oil cup is where the extracted oil will fall into.

Figure 2

Soybeans

Soybeans contain little oil. 500g of local soybeans contains 60-90g of oil;

transgenic soybeans contain 90-125g of oil. You can refer to the steps to press

peanuts for hot pressing, namely, heat soybeans till their skins crack and then

press them.

Rapeseeds

There are two kinds of rapeseeds, winter and spring, both of which contain

30%-40% oil in most cases. Pick fresh and plump rapeseeds. The time of heat-

ing should be reduced since rapeseeds are a small grain. Oil extraction rates of

dierent rapeseeds in dierent regions are quite dierent. Please refer to the

method for pressing camellia seeds. Make sure to drain o any water before

pressing.

Saower Seeds and Fructus Cannabis

The shell of saower seeds or fructus cannabis is very thick and hard. It is best

to shell them before pressing. If they can’t be shelled, make sure to heat the

raw materials and press them when they’re still hot, as suggested by the “hot

pressing” method introduced above.

Turn on the machine for 30 minutes to heat it up rst and then turn on the

pressing switch. Put in a small amount rst and ll the hopper after a normal

amount of slag is detected. Press them one time, and if it backs up, clean out

the pressing chamber and start over.

U.S. Solid® • 1200 E.55th Unit C, Cleveland, OH, 44103 • www.ussolid.com

1. Place oil press on solid level table.

2. Install hopper according to Figure 2. Place the oil cup below the oil outlet

and prepare container for slag.

3. Plug in power supply that corresponds to the socket on the machine.

4. Installation is complete.

Manufacturer tests machine before shipping and then thoroughly cleans the

item. When cleaning yourself, be sure to avoid abrasive materials (toothpaste,

etc.), acid, and alkaline liquid (such as soda water). After cleaning, please

be sure that pressing chamber and screw are totally dry. Moisture can make

material stick on the screw and produce a metal friction noise.

IV. Installation

V. Operating the Machine

The oil press can do two types of pressing: hot pressing and cold pressing.

Before beginning this process, user must make sure raw materials are dry

enough for use. For highest quality oil, only high quality, fresh raw materials

should be used for pressing.

Cold Pressing

If the materials are suciently dry, they do not need to be heated. Preheat the

machine for at least 20 minutes, though more time may be necessary in the

winter. Directly put the raw materials in the hopper.

Hot Pressing

Preheat machine for at least 20 minutes. Heat seeds starting with 5-7 ounces

at a time and blot dry before adding to the hopper. Do not allow seeds to cool

as this will create more slag and possibly cause a blockage in the pressing

chamber.

Note: The aim of heating is to remove excess water and improve the concen-

tration oil. Begin pressing after the raw materials are well heated. If the seeds

are overheated,a paste or powder will come out, and the pressing chamber

will make a friction noise.

Walnut Kernels

Put walnut kernels into a cloth bag and slightly crack them with a wooden

mallet into pieces the size of a regular peanut kernel. Since walnut kernels

contain lots of oil but few bers, they are not that easy to press. Make sure

to add a few soybeans while pressing walnut kernels. The amount you add

should be based on getting a normal amount of slag. To get better oil, heat

walnut kernels with moderate heat using the microwave oven for 2-3 minutes,

or heat them for 10 minutes using the oven but only turning on the upper

heating element at the temperature of 215 °F before pressing.

Good walnuts should be dark in color. Avoid walnuts that have been bleached

and seem overly clean. Bleached walnuts may contain chemicals or preserva-

tives and should not be used for oil pressing. Pick walnuts with a dark color

and heavier weight for the best results in oil pressing.

It is suggested that you try a small amount rst and then buy more if they’re

good. Store the newly pressed walnut oil at room temperature for 24 hours. If

the oil separates and subsides, the walnuts were good ones. If the oil fails to

separate and subside after four or ve days, change the raw material and try

again.

Okra Seeds

Select mature and high-quality okra seeds for pressing. Okra seeds are dier-

ent from other oil plants because their shells are thick and hard. Make sure to

heat them on a low heat setting in the oven, or by using the microwave oven

for 2-3 minutes till they turn soft before pressing. If the shells are already o,

add a few soybeans to the okra seeds. The amount you add should be based

on getting a normal amount of slag.

Pumpkin Seeds

Select plump and mature pumpkin seeds in small and medium sizes (it’s hard

to press very big ones). You may press them cold or after heating, depending

upon your preference.

Sunower Seeds

The best sunower seeds for oil are small and black and contain a lot of oil.

They can be pressed either unshelled or shelled. More oil can be pressed if

sunower seeds are heated before pressing. Please refer to the steps to press

peanuts.

U.S. Solid® • 1200 E.55th Unit C, Cleveland, OH, 44103 • www.ussolid.com

Pressing for Oil

1. Turn on heating switch and wait for 25 minutes; extend the waiting time

appropriately during the cold seasons (never turn it o during the oil

pressing process).

2. Put dry ingredients into the hopper.

3. Press the “Pressing”switch and begin pressing oil.

4. After oil pressing ends, hold the“Cleaning” switch for 20 seconds; it will

be easier to remove the screw and then clean. It is crucial to press the

“Cleaning”button before the machine cools. If the cleaning switch has

not been pressed, after the chamber becomes cold the residual slag hard-

ens and the pressing rod will become blocked.

Note: In case of power outage during the process, please turn o the start

switch and unplug power plug. Once power is reconnected, turn on the heat-

ing switch for at least 30 minutes before continuing the press process.

Common Issues in Pressing

When pressing, any of the following can cause mistakes during the process

and lead to poor oil ow, or low quality oil:

• Raw materials have been stir-fried.

• Raw materials are overcooked (except camellia seeds).

• Raw materials are allowed to cool before pressing.

• Raw materials have been exposed to sunlight (exceptions for peanuts and

camellia seeds).

• Raw materials are overly wet.

• The machine is not properly heated up.

• Heating of raw materials is done with an induction cooker, light wave

stove, or electric radiant cooker.

• Freezer or refrigerator is used for storage of raw materials.

• Usage location is particularly dry.

• If oil and residue splash out at the same time in slag notch, this may be

because raw materials contain too much water. It may also be associated

with unsmooth incoming material or slow pressing.

White or Black Sesame Seeds

Refer to the“peanut pressing method”

White sesame and unshelled sesame must be red till slightly yellow or half

mixed with black sesame (please refer to the hot pressing method).

In many cities, there are a lot of grain stores or supermarkets that sell sesame

seeds and peanuts and provide roasting and milling services at the same time.

Please note that the roasted sesame seeds are intended for grinding, and can

not be used for pressing oil. Only powder will come out, and could result in

the pressing chamber becoming blocked. When buying sesame seeds, please

choose mature, good sesame seeds with full grains to get the most oil out of

them.

Attention!! The oil press is only for pressing oil. It has nothing to do with

whether the oil is aromatic or not. This is decided by the type of raw material

and how the raw material is heated before the pressing. Please refer to meth-

ods in the oil fragrance secret section below.

Oil Fragrance Secret

First boil a proper amount of water. Use about 35 ounces of peanuts or black

sesame (white sesame is not fragrant). Cook until they have a light yellow skin,

using the methods previously described. Be sure not to burn, as burnt oil has

a distinctive, bitter taste.

First boil the water, and then place a clean cloth on the steamer, spread the

heated peanuts or sesame evenly on it, leaving space in the middle to let the

steam rise. Cover it and steam for 5-7 minutes; then take out, mix evenly, and

hot press. Oil can be stored under normal temperature for a long time. This is

a traditional method for creating fragrant oils.

U.S. Solid® • 1200 E.55th Unit C, Cleveland, OH, 44103 • www.ussolid.com

VI. Cleaning the Machine

1. Shut o the power and unplug the machine.

2. If pressing chamber is hot, wear cotton, heat-protective gloves to prevent

burns. Alternatively, wait for 60 minutes to let the pressing chamber cool

down completely.

3. According to the graphic below, remove the lock from the pressing

chambe.

4. Take out the pressing rod.

5. Clean it and then rinse.

6. Clean the pressing chamber with water.

Putting the Machine Back Together

• Screw the stem casting into the bearing.

• Attach the external pressing chamber.

• Screw the four nuts on by hand.

• Gently tighten them with the wrench.

Note: Never over-tighten the four nuts.

Peanuts

First conrm the quality of peanuts. To conrm dryness, press peanut kernels and if at

least one-third of the red skin falls o then they are dry enough. Fresh and dry enough

peanut kernels are t for oil pressing directly. Peanuts in storage for a long time can

be recognized by a grayness to their skin, and the lack of sweet avor. It is important

to use peanuts stored for less than a year, which can be found at many rice and grain

stores. You can start out buying a small amount of peanuts in several dierent places

to determine which peanut is best for pressing out oil. As always, heat the machine

for twenty minutes. With peanuts, then proceed to cold pressing. There are several

possible outcomes for oil pressing with peanuts:

• Oil output is normal; oil separates after being placed at room temperature for 24

hours or more. This shows the peanuts were good.

• Oil output is normal; the oil does not separate after 24 hours. This means the

peanuts were bad. Replace them and try again.

• Only powder comes out, showing that there is no water at all; this situation prone

to occur in dry areas and winter time. Please add water by soaking your hands,

then stirring the peanuts with your soaked hands. If there are a lot of peanuts,

undertake this process repeatedly.

You can press oil normally after conrmation of proper functioning.

Notice: When rinsing peanuts, the longest rinse time must not exceed 5 minutes. After

draining, remove moisture through heating before use. Press all of them while they

are still warm. Otherwise, peanuts will absorb too much water and oil will inject in

slag notch. It is hard to dry out washed peanuts in the sun, and it can ruin the peanuts.

This tends to cause more slag and oil injection. It is best to directly cook the washed

peanuts until dry.

Note: When heating with a microwave oven, many plates will absorb the heat resulting

in a plate that is hot and peanuts that are not. To avoid this, please use microwavable

plates.

Peanuts should be heated in a microwave oven on medium heat. They should be heat-

ed until one minute after hearing a ‘pop-pop’noise. This usually takes about three min-

utes, but will vary with experience. If the materials are wet, increase time accordingly.

If heating, instead, with an oven, use an oven with a rotating cage and only turn on the

upper heater. Adjust the time to about 20 minutes if using this heating style. Time will

be increased or decreased depending on dryness of the raw material. Ovens without

cages tend to lead to burnt or otherwise unusable raw materials.

U.S. Solid® • 1200 E.55th Unit C, Cleveland, OH, 44103 • www.ussolid.com

VII. Processing and Storing Oil

Because the oil that is pressed out contains liquid from the raw materials, the

coloration of the oil will vary with the material used. Peanut oil, walnut oil,

and white sesame oil should appear a light ivory. Black sesame oil will appear

a light black. The colors of these liquids will change depending on heat used

during the drying out process.

Once the oil is pressed from the raw material, store it at room temperature

overnight. The oil will naturally separate from the other liquids without any

ltering. The longer you store your mixture at room temperature, the more

complete the separation will be. Once the oil is completely separated, you can

bottle it and store in your fridge, or keep it at room temperature. It is recom-

mended to use oils within 60 days of pressing.

Note: The oil quality will be a reection of the raw materials used. Raw ma-

terials of low quality, aged, or kept in poor conditions, will yield cloudier and

lower quality oil. Therefore it is important to use the best quality raw materials

possible for oil pressing.

The heating temperature and control of the raw materials is a vital part of

the process. Microwave ovens are the preferred method for heating. Items

should be heated until soft to the bite. A 3 minute heating is a good start

time, though times will vary dependent on the raw material used and the age

of the material.

Raw materials should never be put into the machine when wet. This will lead

to damage of the machine, and inecacy of oil extraction. Similarly, overly

dry materials will not produce oil, instead a dry powder. If this happens, stop

pressing immediately.

To avoid these occurrences, start with small quantities of raw materials, to

make sure the heating time you use is appropriate.

Additionally, limit the quantities of raw materials used. Using an excessive

amount will allow some to cool while in the hopper, which will lead to mal-

function.

VIII. Preparing the Raw Materials

IX. Raw Material Guide

Camellia seeds

Camellia seeds are special. They can be dried out enough for pressing with

only exposure to sunlight. In case this does not do the trick, or there is no am-

ple sunlight, they can be put into the microwave and heated for 3-4 minutes,

roughly 35 oz. at a time. Before pressing these seeds, larger pieces should

be broken into pieces the size of a peanut kernel. Do not crush the seeds to

be too small, as they will be unable to enter the chamber themselves. For

camellia seeds, press them after they have cooled, but use a small amount at

rst. There can be large variations in moisture content in camellia seeds, and

using small batches reduces this problem. There should be no water left in

the camellia seeds during pressing, and it should produce yellow colored slag,

which is an indication of optimal oil extraction.

Flaxseed

Flaxseed dier from other seeds because they also contain a layer of jelly. The

longer they are stored, the higher the viscosity of the axseed gum becomes.

Lower temperatures also contribute to higher viscosity and less oil extraction.

If either of these conditions are present, there is a possibility of no oil being

extracted, instead only powder.

When pressing axseed, rst turn on the heating switch and heat for 20 min-

utes. You can turn o the heating during hot days (just don’t shut o it during

cold days or if the axseed have been stored for a long period, otherwise only

powder comes out). Put raw materials in and start pressing. Because of their

layer of jelly, during cold days, even though you heat them, powder tends to

come out at the oil outlet. You can rst pre-heat the raw materials and then

press them. If oil overows in the slag notch or outows from the four screws

at the pressing chamber, please dry the axseeds or mix them with 10-20%

cooked soybeans (eating raw soybean oil can cause diarrhea). Add a suitable

proportion of soybeans until there is no overow. Slowly add more soybeans

if necessary and take advantage of the characteristics (less oil) of soybeans to

bring the water out.

Note: No matter which raw material is used, if oil overows in the slag notch,

or overows from the 4 screws of the pressing chamber, the raw material

contain too much water. Clean the pressing chamber, dry the moisture, and

then remove moisture from the raw material according to the “hot pressing”

method.
